oauthlib 3.0 was released Jan 8 2019, the current upstream is 3.0.2 released July 4 2019.
python-requests-oauthlib has a dependency on python-oauthlib >= 3.0 as well as a few other packages I believe. The dependency on python-oauthlib in python-requests-oauthlib was not caught when python-requests-oauthlib was updated in rawhide and F30, this needs to get fixed.
python-requests-oauthlib is the only one that requires >= 3.0 as far as I can tell. All the rest use the OAuth1 interface, which wasn't changed much in 3.0 (just a new cypher added).
I'm going to update this wed unless I hear otherwise from anyone.
Rawhide (F31 at the moment) is now updated with oauthlib 3.0.2
The dependency on oauthlib from >=2.1.0 to >=3.0.0 occurred in requests-oauthlib 1.2.0, not in 1.0.0 as I had mistakenly feared. F30 has 1.0.0 not 1.2.0 so I think we're safe because F30 still has oauthlib 2.1.0, therefore I believe F30 is O.K. with respect to version dependencies.
